Organochlorine residues in Dall's and True's porpoises collected from North-western Pacific and adjacent waters
The levels of organochlorine residues (PCB and p, p′-DDE) in the adult male Dalli and Truei porpoises collected from North Pacific, Bering Sea and Japan Sea are reported. Different levels of these compounds were observed in the individuals with respect to sex and location, indicating the fact that m...
